Today: Not-So-Smart Bombs. Vaping and Teens.

Hello. I'm Davan Maharaj, the editor of the Los Angeles Times. Here are some story lines you shouldn't miss today.

TOP STORIES

Not-So-Smart Bombs

It sounds so familiar: "Precision" airstrikes begin to rack up civilian casualties. This time it's the Saudis bombing Houthi rebels in Yemen. The Houthis aren't budging. "It's a disaster," one U.S. official says, bemoaning lack of "a realistic endgame." Al Qaeda's Yemen affiliate, meanwhile, is using the chaos to seize ground. The U.S. hopes more advisors and smart-bomb tech will help.

Boko Haram and the Smell of Death

"The whole town smelled of death,” said Mariam Adam, a midwife. “What really affected me is the way that we women had to bury the men. It’s something I’ll never forget in my life.” Few correspondents get accounts from towns ravaged by Boko Haram, the Nigerian extremist group. Our Africa correspondent, Robyn Dixon, learns the story from those who escaped. When Boko Haram took over a northern Nigerian city last year, men and boys as young as 10 were rounded up and shot, beheaded or burned alive. When the bloodbath stopped three days later, the streets were full of women pushing their dead sons, husbands, fathers and brothers in carts and wheelbarrows.

Vaping and the American Teen

With colorful designs and candy-store flavors, e-cigarettes seem designed to hook kids on nicotine. This just in: It's working. In 2011, only 1.5% of high school students were using vaping devices. By 2014, it had ballooned to 13.4%, a federal report says. That threatens to wipe out hard-won gains in the fight against teen smoking. Experts worry e-cigs are becoming a “gateway drug” that may steer teens toward tobacco.

The Art of Internment

Nancy Oda, who was born in a Tule Lake relocation camp during World War II, was furious. So were other Japanese Americans when they learned an auction house was selling off art works made in such camps -- brooches, name plates, watercolors, carvings. "This is wrong to sell our memories," Oda said. Read how the sale was halted and how the auction house is responding.

The Tricks of Trade

We may have to stop calling them "rare" bipartisan deals. Congressional leaders reached another one to give President Obama "fast-track" powers to cut a trade pact with Pacific nations. It's central to Obama's tilt toward Asia, where China is flexing its muscle, but some Democrats worry it will cost U.S. jobs. Republicans like it, though. Another big backer: Hollywood.

Hollywood and the Art House: The gripe against Hollywood used to be that its stars and power players weren’t particularly generous to local arts institutions. Not anymore. The Los Angeles County Museum of Art, once a bastion of old money, has become a darling of the entertainment industry. The guest list for its 50th anniversary gala could easily be mistaken for a Hollywood awards show. The museum’s board of trustees members are younger and more connected to Hollywood than ever. This is no accident. David Ng explains how LACMA, in the words of longtime trustee Lynda Resnick, “totally morphed into a different place.”

Demon Almonds: It's not clear when they became the scapegoat for California's drought, but a seminal moment was the assertion that it takes 1.1 gallons of water to make one nut. That's actually misleading, Columnist Robin Abcarian discovers (others claim it takes 106 gallons to make an ounce of beef). Read what happens when she gives almond farmers a chance to vent.
